Covers PostgreSQL, MySQL, MongoDB with Prisma, TypeORM, Drizzle, and SQLAlchemy, plus Testcontainers test databases. Use when: "database test," "migration test," "migration rollback," "rollback test," "data integrity," "SQL test," "schema validation," "seed data," "query performance," "Testcontainers."

Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.
What the file says
<objective> A migration that passes `prisma migrate deploy` can still silently drop a column's data, and an `EXPLAIN` assertion that never fails will green-light a query that lost its index — both ship to production looking fine. This skill produces database tests that catch those: forward AND backward migration tests, constraint-rejection tests, deterministic seed data, drift detection, and query-plan assertions that actually fail when the index disappears. **Before starting:** check `.agents/qa-project-context.md` for database type, ORM, migration tooling, and environment config — they shape every pattern below. </objective> --- ## Discovery Questions Check `.agents/qa-project-context.md` first — if it exists, use it and skip anything already answered there. Then: 1. **Database type:** PostgreSQL, MySQL, SQLite, MongoDB, or multi-database? Each has different constraint syntax, migration tools, and performance profiling. 2. **ORM / query builder:** Prisma, TypeORM, Drizzle, Sequelize, SQLAlchemy, Django ORM, or raw SQL? The ORM determines migration tooling and test patterns. …

How to install
mdr add petrkindlmann/qa-skills/database-testing@sha256:20ef5ba9aac22e4aThe line at the top of this page pins the label v2.0, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
